Yes, parents with blood group O positive can have a child with blood group O negative. This is possible if one parent is heterozygous for the Rh factor (one parent has both positive and negative Rh alleles), allowing for the possibility of the child inheriting the negative Rh factor.
Actually it could happen if one of the parents was a chimera but the chances of that being the casewould be rare.

Yes, blood type has no bearing on weather or not the parents can have a child

Can a child with RH neg blood come from parents that are A positive and A negative
if both parents have positive o blood their child must have positive o blood
Both parents having the same blood type should never be an issue. There can be issues when one parent is a neg and the other is a positive. The issue is rare though.
If both parents have a positive blood type, the chances of their child inheriting a positive blood type are 100.
Being positive - having a certain antibody on your blood cells - says nothing about anything except whether your parents were positive or not (and even then, exactly what they had cannot be determined solely from that information).
No, there is no risk at all.
Another has said: no chance. One of the parents must be b positive.
